Abstract Objective To assess seizure and developmental outcomes, their predictors, and complications in 160 children who, between 1998 and 2022, underwent surgery for lesional epilepsy with curative intent before the age of 3 years. To compare trends in epilepsy surgery in this age group before and after the year 2014. Methods Retrospective multicenter study. Descriptive and univariate analyses, and multivariable models for all outcomes. Results These 160 patients (76 F; 47.5%) underwent 169 surgeries (age at surgery 20.4 ± 9.4 months). At the last follow‐up (77 ± 57.4 months), 121 patients (75.6%) were in Engel class I, 106 (66.2%) of whom were in Engel class Ia. Antiseizure medications were stopped in 84 patients (52.5%). Complications requiring reoperations were observed in 16 patients (10%; 9.5% of surgeries) and unexpected permanent deficits in 12 (7.5%; 7.1% of surgeries). Postoperative cognitive functions remained unchanged in 56 patients (44.4%), improved in 51 (40.5%), and worsened in 19 (15.1%). Multivariable analyses showed that the probability of achieving Engel class Ia was lower when the duration of epilepsy was longer, patients underwent preoperative video‐EEG, and unexpected postoperative permanent deficits occurred. Cognitive improvement after surgery was associated with lower preoperative seizure frequency, better preoperative developmental level, and a longer postoperative follow‐up. FCDII and tumors were the histopathologies carrying a higher probability of achieving seizure freedom, while polymicrogyria was associated with a lower probability of cognitive improvement. The number of patients operated on after 2014 was higher than before (61.3% vs. 38.7%), with stable outcomes. Significance Epilepsy surgery is effective and safe in infants and toddlers, although the complication rate is higher than seen in older patients. Shorter duration of epilepsy, lower seizure frequency, no need for video‐EEG, tumors, and some malformations of cortical development are robust predictors of seizure and cognitive outcome that may be exploited to increase earlier referral. Plain Language Summary This study analyzed the results of epilepsy surgery in 160 children who had been operated on before the age of 3 years at four Italian centers between 1998 and 2022. At the last follow‐up (77 ± 57.4 months), 121 patients (75.6%) were free from disabling seizures, of which 106 (66.2%) were completely seizure‐free since surgery. Major surgical complications occurred in 28 patients (17.5%), which is higher than observed with epilepsy surgery in general, but similar to hemispheric/multilobar surgery. Postoperative cognitive function remained unchanged in 56 patients (44.4%), improved in 51 (40.5%), and worsened in 19 (15.1%). Epilepsy surgery is effective and safe in infants and toddlers.

ABSTRACT Objectives: to understand nurse perspectives regarding homeless pregnant women’s accessibility to prenatal care. Methods: a qualitative study, with analysis based on the concept of accessibility. Semi-structured interviews were carried out with 11 nurses who work at the Street Outreach Office in northern Brazil. Results: nurses are faced with geographic barriers and dangerous situations in border regions, recognizing that there is a context of physical, sexual and psychological violence that involves homeless pregnant women who seek care at the Street Outreach Office. Street Outreach Office nurses’ work occurs in conjunction with other services in the Health Care Network. The implementation of educational measures is a powerful strategy, as is establishing links with women. Final Considerations: the Street Outreach Office’s work provides meetings with pregnant women on site in the territory, which can provide geographic and socio-organizational accessibility to prenatal care.

Background: One of the common complications after total knee arthroplasty (TKA) is periprosthetic joint infection (PJI). The differential diagnosis should include allergies to implant components or cement constituents, for which the clinical manifestation may mimic an infection. An allergic skin reaction to suture material after TKA mimicking acute PJI has to date never been described in the literature. Case report: We present a case of acute allergic skin reaction to polydioxanone suture material (Stratafix™, Ethicon, Johnson & Johnson) initially suspected to be acute PJI one week after TKA. The patient was treated with debridement, extensive synovectomy, irrigation and implant retention followed by antibiotic therapy. The bacteriological analysis was negative and the histological examination of the excised wound showed Wells-type eosinophilic cellulitis. The definitive diagnosis was an allergic reaction to sutures mimicking an acute PJI. Conclusion: An allergic skin reaction to suture material mimicking acute PJI has an extremely low incidence and therefore has been barely described. The different clinical presentations complicate diagnosis and treatment decisions, particularly in acute settings. The formal diagnosis is made by histopathological analysis of wound tissue in the presence of negative microbiological cultures. We may consider wound biopsy during or before surgical revision as an additional tool in PIJ strategy work-up.

Cardiovascular diseases are among the leading causes of mortality worldwide, with dietary factors being the main risk contributors. Diets rich in bioactive compounds, such as (poly)phenols, have been shown to potentially exert positive effects on vascular health. Among them, resveratrol has gained particular attention due to its potential antioxidant and anti-inflammatory action. Nevertheless, the results in humans are conflicting possibly due to interindividual different responses. The gut microbiota, a complex microbial community that inhabits the gastrointestinal tract, has been called out as potentially responsible for modulating the biological activities of phenolic metabolites in humans. The present review aims to summarize the main findings from clinical trials on the effects of resveratrol interventions on endothelial and vascular outcomes and review potential mechanisms interesting the role of gut microbiota on the metabolism of this molecule and its cardioprotective metabolites. The findings from randomized controlled trials show contrasting results on the effects of resveratrol supplementation and vascular biomarkers without dose-dependent effect. In particular, studies in which resveratrol was integrated using food sources, i.e., red wine, reported significant effects although the resveratrol content was, on average, much lower compared to tablet supplementation, while other studies with often extreme resveratrol supplementation resulted in null findings. The results from experimental studies suggest that resveratrol exerts cardioprotective effects through the modulation of various antioxidant, anti-inflammatory, and anti-hypertensive pathways, and microbiota composition. Recent studies on resveratrol-derived metabolites, such as piceatannol, have demonstrated its effects on biomarkers of vascular health. Moreover, resveratrol itself has been shown to improve the gut microbiota composition toward an anti-inflammatory profile. Considering the contrasting findings from clinical studies, future research exploring the bidirectional link between resveratrol metabolism and gut microbiota as well as the mediating effect of gut microbiota in resveratrol effect on cardiovascular health is warranted.

Abstract Background Homeless women have complex life conditions and are often exposed to violence, sexual exploitation, rape, prostitution, reproductive disorders, survival sex trading, unintended pregnancies and sexually transmitted infections (STIs). The aim was to explore the existence of sexual aggression and vulnerability to STIs among homeless Brazilian women. Methods Fifteen interviews were conducted with homeless women who were admitted to a women’s shelter in a large city in Brazil. Data were collected through semi-structured interviews, audiorecorded and complemented with notes of the researcher in field diary, subjected to inductive thematic analysis and analyzed in light of the social relations of gender. Results Two themes were constructed: “Being a woman on the streets: a look at gender inequalities” and “Pain and the raped body: the scars of homeless women”. The transgression of women’s rights was observed with reports of sexual abuse interspersed with physical violence. Unprotected sexual practices were part of the daily lives of these women, with repercussions for their exposure to sexually transmitted infections. Dependence on psychoactive substances was mentioned, and transactional sex was used as a source of income to maintain such dependence, as well as to promote the women’s livelihood. Conclusion Homeless women experience complex situations on the streets involving exposure to different types of violence, the use of transactional sex as a survival strategy and unprotected sexual practices. Furthermore, the way in which women have been exposed to sexual assault and their coping mechanisms to those require attention. Interventions are need to improve the healthcare assistance of homeless women victims of sexual assault, considering the vulnerability of this population.

Background: Treatment outcomes in intermediate-risk prostate cancer (PCa) may be impaired by adverse pathology misclassification including tumor upgrading and upstaging. Clinical predictors of disease progression need to be improved in this category of patients. Objectives: To identify PCa prognostic factors to define prognostic groups in intermediate-risk patients treated with robot-assisted radical prostatectomy (RARP). Design: Data from 1143 patients undergoing RARP from January 2013 to October 2020 were collected: 901 subjects had available follow-up, of whom 479 were at intermediate risk. Methods: PCa progression was defined as biochemical recurrence and/or local recurrence and/or distant metastases. Study endpoints were evaluated by statistical methods including Cox’s proportional hazards, Kaplan–Meyer survival curves, and binomial and multinomial logistic regression models. Results: After a median (interquartile range) of 35 months (15–57 months), 84 patients (17.5%) had disease progression, which was independently predicted by the percentage of biopsy-positive cores ⩾ 50% and the International Society of Urological Pathology (ISUP) grade group 3 for clinical factors and by ISUP > 2, positive surgical margins and pelvic lymph node invasion for pathological features. Patients were classified into clinical and pathological groups as favorable, unfavorable (one prognostic factor), and adverse (more than one prognostic factor). The risk of PCa progression increased with worsening prognosis through groups. A significant positive association was found between the two groups; consequently, as clinical prognosis worsened, the risk of detecting unfavorable and adverse pathological prognostic clusters increased in both unadjusted and adjusted models. Conclusion: The study identified factors predicting disease progression that allowed the computation of highly correlated prognostic groups. As the prognosis worsened, the risk of PCa progression increased. Intermediate-risk PCa needs more prognostic stratification for appropriate management.

Synchrotron radiation offers a host of advanced properties, surpassing conventional laboratory sources with its high brightness, tunable phonon energy, photon beam coherence for advanced X-ray imaging, and a structured time profile, ideal for capturing dynamic atomic and molecular processes. However, these benefits come at the cost of operational complexity and expenses. Three decades ago, synchrotron radiation facilities, while technically open to all scientists, primarily served a limited community. Despite substantial accessibility improvements over the past two decades, synchrotron measurements still do not qualify as routine analyses. The intrinsic complexity of synchrotron science means experiments are pursued only when no alternatives suffice. In recent years, strides have been made in technology transfer offices, intermediate synchrotron-based analytical service companies, and the development of high-throughput synchrotron systems at various facilities, reshaping the perception of synchrotron science. This article investigates the practical application of synchrotron X-Ray Powder Diffraction (s-XRPD) techniques in pharmaceutical analysis. By utilizing concrete examples, we demonstrate how high-throughput systems have the potential to revolutionize s-XRPD applications in the pharmaceutical industry, rapidly generating XRPD patterns of comparable or superior quality to those obtained in state-of-the-art laboratory XRPD, all in less than 5 s. Additional cases featuring well-established pharmaceutical active ingredients (API) and excipients substantiate the concept of high throughput in pharmaceuticals, affirming data quality through structural refinements aligned with literature-derived unit cell parameters. Synchrotron data need not always be state-of-the-art to compete with lab-XRPD data. The key lies in ensuring user-friendliness, reproducibility, accessibility, cost-effectiveness, and the streamlined efforts associated with synchrotron instrumentation to remain highly competitive with their laboratory counterparts.

ABSTRACT This study aimed to compare genitourinary symptoms and quality of life in women with breast cancer before and after chemotherapy treatment. This is a prospective and analytical study carried out with 60 women treated at a hospital in the state of Paraná. Sociodemographic data, menopausal status, climacteric symptoms, quality of life, and pelvic floor strength and resistance were collected. Descriptive statistics, t-tests, Shapiro-Wilk, Cochran, Factorial Analysis of Variance for Repeated Measures and Fishers least significance difference were used for data analysis. Participants suffered genitourinary alterations, such as reduced strength and resistance of the pelvic floor muscles, urinary incontinence and vulvovaginal atrophy, regardless of the evaluated factors (type of chemotherapy, parity, and menopausal status). Therefore, greater attention and discussion by multidisciplinary health teams is necessary, as these symptoms can be reduced and managed if recognized early.

Objectives: To develop a mutation-based radiomics signature to predict response to imatinib in Gastrointestinal Stromal Tumors (GISTs). Methods: Eighty-two patients with GIST were enrolled in this retrospective study, including 52 patients from one center that were used to develop the model, and 30 patients from a second center to validate it. Reference standard was the mutational status of tyrosine-protein kinase (KIT) and platelet-derived growth factor α (PDGFRA). Patients were dichotomized in imatinib sensitive (group 0 - mutation in KIT or PDGFRA, different from exon 18-D842V), and imatinib non-responsive (group 1 - PDGFRA exon 18-D842V mutation or absence of mutation in KIT/PDGFRA). Initially, 107 texture features were extracted from the tumor masks of baseline computed tomography scans. Different machine learning methods were then implemented to select the best combination of features for the development of the radiomics signature. Results: The best performance was obtained with the 5 features selected by the ANOVA model and the Bayes classifier, using a threshold of 0.36. With this setting the radiomics signature had an accuracy and precision for sensitive patients of 82 % (95 % CI:60–95) and 90 % (95 % CI:73–97), respectively. Conversely, a precision of 80 % (95 % CI:34–97) was obtained in non-responsive patients using a threshold of 0.9. Indeed, with the latter setting 4 patients out of 5 were correctly predicted as non-responders. Conclusions: The results are a first step towards using radiomics to improve the management of patients with GIST, especially when tumor tissue is unavailable for molecular analysis or when molecular profiling is inconclusive.

Abstract Early‐life stress can result in life‐long effects that impact adult health and disease risk, but little is known about how such programming is established and maintained. Here, we show that such epigenetic memories can be initiated in the Drosophila embryo before the major wave of zygotic transcription, and higher‐order chromatin structures are established. An early short heat shock results in elevated levels of maternal miRNA and reduced levels of a subgroup of zygotic genes in stage 5 embryos. Using a Dicer‐1 mutant, we show that the stress‐induced decrease in one of these genes, the insulator‐binding factor Elba1, is dependent on functional miRNA biogenesis. Reduction in Elba1 correlates with the upregulation of early developmental genes and promotes a sustained weakening of heterochromatin in the adult fly as indicated by an increased expression of the PEV wm4h reporter. We propose that maternal miRNAs, retained in response to an early embryonic heat shock, shape the subsequent de novo heterochromatin establishment that occurs during early development via direct or indirect regulation of some of the earliest expressed genes, including Elba1.

We introduce an innovative theoretical framework tailored for the analysis of Pair Distribution Function (PDF) data derived from Small-Angle X-ray Scattering (SAXS) measurements of core-shell micelles. The new approach involves the exploitation of the first derivative of the PDF and the derivation of analytical equations to solve the core-shell micelle structure under the hypothesis of a spheroidal shape. These analytical equations enable us to determine the micelle’s aggregation number, degree of ellipticity, and contrast in electron density between the core-shell and shell-buffer regions after having determined the whole micelle size and its shell size from the analysis of the first derivative of the PDF. We have formulated an overdetermined system of analytical equations based on the unknowns that characterize the micelle structure. This allows us to establish a Figure of Merit, which is utilized to identify the most reliable solution within the system of equations.

Abstract. Objectives. To test hypothesized associations between the ABO blood group (ABO-bg) system and the pathological features of prostate cancer (PCa). Material and methods. Between January 2013 and September 2019, 1173 patients underwent radical prostatectomy. Associations between ABO-bg levels and pathological features were evaluated using statistical methods. Results. Overall, 1149 consecutive patients were evaluated using the ABO-bg system, which was represented by O-bg (42.8%) and A-bg (41.3%), followed by B-bg (11.1%) and AB-bg (4.8%). Only positive surgical margins (PSMs) was correlated with ABO-bg (Pearson correlation coefficient, r = 0.071; p = 0.017), and the risk was increased in group-O (odds ratio [OR], 1.497; 95% confidence interval, 1.149–1.950; p = 0.003) versus non–O-bg. In clinical and pathological models, O-bg was at increased risk of PSM after the adjustment for prostate-specific antigen, percentage of biopsy-positive cores, and high surgical volume (adjusted OR, 1.546; 95% confidence interval, 1.180–2.026; p = 0.002); however, the adjusted OR did not change after the adjustment for tumor load and stage as well as high surgical volume. Conclusions. In clinical PCa, the risk of PSM was higher in O-bg versus non–O-bg patients after the adjustment for standard predictors. Confirmatory studies are needed to confirm the association between ABO-bg and unfavorable PCa features.

Abstract Percutaneous thermal ablation (PTA), resection, and liver transplantation are the standard curative options for hepatocellular carcinoma (HCC). Liver transplantation yields the best long‐term outcomes but is limited by graft shortage. Thus, patients with ≤3‐cm HCC are primarily treated by PTA even though recurrence is frequent and may occur outside transplant criteria. Data on non‐transplantable recurrence (NTR) following PTA are lacking, however. We therefore investigated the incidence and predictors of NTR among 213 potentially transplantable patients (cirrhosis, 93%; Child‐Pugh A, 98.6%; alcohol‐related disease, 62%) with ≤3‐cm HCC(s) treated by PTA, to stratify them according to their NTR risk and to improve treatment allocation. During follow‐up (median: 41.2 months), NTR occurred in 18.3% (alpha‐fetoprotein [AFP] model) and 23% (Milan) patients. NTR prediction with competing‐risk analysis and internal validation revealed AFP > 100 ng/ml (subdistribution hazard ratio: 7.28; p

Isoflavones are a group of (poly)phenols, also defined as phytoestrogens, with chemical structures comparable with estrogen, that exert weak estrogenic effects. These phytochemical compounds have been targeted for their proven antioxidant and protective effects. Recognizing the increasing prevalence of cardiovascular diseases (CVD), there is a growing interest in understanding the potential cardiovascular benefits associated with these phytochemical compounds. Gut microbiota may play a key role in mediating the effects of isoflavones on vascular and endothelial functions, as it is directly implicated in isoflavones metabolism. The findings from randomized clinical trials indicate that isoflavone supplementation may exert putative effects on vascular biomarkers among healthy individuals, but not among patients affected by cardiometabolic disorders. These results might be explained by the enzymatic transformation to which isoflavones are subjected by the gut microbiota, suggesting that a diverse composition of the microbiota may determine the diverse bioavailability of these compounds. Specifically, the conversion of isoflavones in equol—a microbiota-derived metabolite—seems to differ between individuals. Further studies are needed to clarify the intricate molecular mechanisms behind these contrasting results.

Future GRACE-like geodesy missions could benefit from adopting accelerometer technology akin to that of the LISA Pathfinder, which employed laser interferometric readout at the sub-picometer level in addition to the conventional capacitive sensing, which is at best at the level of 100 pm. Improving accelerometer performance holds great potential to enhance the scientific output of forthcoming missions, carrying invaluable implications for research in climate, water resource management, and disaster risk reduction. To reach sub-picometer displacement sensing precision in the millihertz range, laser interferometers rely on suppression of laser-frequency noise by several orders of magnitude. Many optical frequency stabilization methods are available with varying levels of complexity, size, and performance. In this paper, we describe the performance of a Mach–Zehnder interferometer based on a compact monolithic optic. The setup consists of a commercial fiber injector, a custom-designed pentaprism used to split and recombine the laser beam, and two photoreceivers placed at the complementary output ports of the interferometer. The structural stability of the prism is transferred to the laser frequency via amplification, integration, and feedback of the balanced-detection signal, achieving a fractional frequency instability better than 6 parts in 1013, corresponding to an interferometer pathlength stability better than 1pm/Hz. The prism was designed to host a second interferometer to interrogate the position of a test mass. This optical scheme has been dubbed “single-element dual-interferometer” or SEDI.

The number of publications in the field of chemical cross-linking combined with mass spectrometry (XL-MS) to derive constraints for protein three-dimensional structure modeling and to probe protein-protein interactions has increased during the last years. As the technique is now becoming routine for in vitro and in vivo applications in proteomics and structural biology there is a pressing need to define protocols as well as data analysis and reporting formats. Such consensus formats should become accepted in the field and be shown to lead to reproducible results. This first, community-based harmonization study on XL-MS is based on the results of 32 groups participating worldwide. The aim of this paper is to summarize the status quo of XL-MS and to compare and evaluate existing cross-linking strategies. Our study therefore builds the framework for establishing best practice guidelines to conduct cross-linking experiments, perform data analysis, and define reporting formats with the ultimate goal of assisting scientists to generate accurate and reproducible XL-MS results.

In accordance with European regulation, medicines containing a new active substance to treat neurodegenerative diseases as well as autoimmune and other immune dysfunctions must be approved by the European Medicines Agency (EMA) through the centralized procedure before they can be marketed. However, after EMA approval, each country is responsible for national market access, following the assessment performed by health technology assessment (HTA) bodies with regard to the therapeutic value. This study aims to provide a comparative analysis of HTA recommendations issued by three EU countries (France, Germany, and Italy) for new drugs for multiple sclerosis (MS) following EMA approval. In the reference period, we identified 11 medicines authorized in Europe for MS, including relapsing forms of MS (RMS; n = 4), relapsing–remitting MS (RRMS; n = 6), secondary progressive MS (SPMS; n = 1), and the primary progressive form (PPMS; n = 1). We found no agreement on the therapeutic value (in particular, the “added value” compared to the standard of care) of the selected drugs. Most evaluations resulted in the lowest score (“additional benefit not proven/no clinical improvement”), underlining the need for new molecules with better efficacy and safety profiles for MS, especially for some forms and clinical settings.

Objetivo: investigar o direito da mulher acima dos 35 anos ao planejamento familiar, uma vez que a partir dessa faixa etária o exercício do direito reprodutivo poderá trazer riscos à sua saúde e à do feto. Metodologia: tratou-se de uma pesquisa baseada em revisão bibliográfica narrativa e descritiva, utilizando-se de artigos publicados em periódicos especializados em ciências da saúde e em direito à saúde, livros e coletâneas. Para os artigos, foram utilizados os seguintes descritores, em especial, nas plataformas Google Acadêmico, EBSCO e Periódicos CAPES: maternidade tardia; riscos da maternidade tardia; maternidade tardia e mercado de trabalho. Resultados: observou-se que o corpo da mulher a partir dos 35 anos de idade já não está mais tão apto à maternidade como o da mulher entre os 20 e 29 anos, idade considerada ideal para a procriação. Ao adiar a maternidade, pelos mais variados motivos, a mulher coloca-se frente a frente a uma gravidez de risco, em razão dos graves problemas de saúde que poderão ocorrer durante a gestação, fazendo com que essa gravidez seja considerada de alto-risco tanto para ela quanto para o bebê. Conclusão: a mulher que opta por adiar a maternidade deve ser devidamente informada pelo profissional da saúde especializado em reprodução humana, artificial ou não, sobre os graves problemas que a gravidez tardia pode causar a ela e ao bebê.

Abstract Endovascular aneurysm repair (EVAR) is a minimally invasive treatment proposed as an alternative to open repair in patients with abdominal aortic aneurysms. EVAR consists in a stent-graft placement within the aorta in order to exclude the aneurysm from arterial circulation and reduce the risk of rupture. Knowledge of the various types of devices is mandatory because some stents/grafts are more frequently associated with complications. CT angiography is the gold standard diagnostic technique for preprocedural planning and postprocedural surveillance. EVAR needs long-term follow-up due to the high rate of complications. Complications can be divided in endograft device-related and systemic complications. The purpose of this article is to review the CT imaging findings of EVAR complications and the key features for the diagnosis.

The massive diffusion of social media has produced disintermediation and it has changed the way in which users inform themselves and participate in public debate. On the other hand, users show a tendency to interact with information that adheres to personal choices and previous opinions. This propensity is “exploited” by algorithms that manage and sort communication on social media, increasingly producing a polarized audience. The essay shows the outcomes of these dynamics by focusing on the communications structure related to the pandemic. In this sense, social media constitute a risk because they convey out-of-control access to unreliable information and because they can result in the absence of correct information, if not in a problem for democracy. On the technical level, at least three complex reticular structures are identified that evolve following different directions, emerged from three sequentially monitored lemmas (no-mask, covid-19, greenpass). Further considerations concern the increasingly dense interweaving between online communication and the genesis of protest movements with evanescent, single-issue structures.

PurposeThe study aimed to analyze the influence of chemotherapy on health biomarkers and examine the relationship between phase angle (PhA) and oxidative stress.MethodsA prospective study was performed. Women who were starting chemotherapy were recruited. Also, this study included a control group of women without cancer. Bioelectrical impedance multiple-frequency (BIS) analysis, 24h food recall, and blood samples were collected at 2-time points: diagnosis (T0) and after one month of completion of therapy (T1) for the main study group and one-time point for the control group. T-tests or Mann-Whitney Wilcoxon Test was used to compare variables. Linear regression analysis was conducted to test if PhA is related to the dependent variables after adjusting for age and body mass index.Results119 women were included (61 with breast cancer and 58 healthy). There was no difference between the groups concerning anthropometrics, fat mass, and fat-free mass. Breast cancer patients had a worsening in PhA (pConclusionOur findings show that PhA is an easy and affordable tool that correlates oxidative stress markers in breast cancer patients, regardless of age or body mass index.

This study focuses on the analysis of contacts and communications on Twitter concerning pandemic policies. The goal is both show mobilization processes rising from the web and detect main actors, themes, and contents within the European context. Through a mixed method procedure, we tried to identify the main themes and most relevant communities, the main users, the most relevant topics and languages, and the underlined meanings and differences related to languages (as proxies of areas). Monitoring the communication on 3 main topics (“no-mask”, “covid-19”, “greenpass”), we noticed the weight of the gap between the government's attempts to communicate information motivating measures geared toward managing the crisis and the perceptions of private users. These perceptions spread through the web with such force the more the emotional, ironic, or polemical plane weighs. In this sense, online communication could be considered a tool for understanding the weight of the interaction between the institutional, social, and private dimensions, with effects on the social construction of identities. Digital communication is becoming an element of this process. The paper describes the “reassuring” role played by the digital community in the construction of ontological forms of security resulting from the construction of a shared digital culture. Results show the emergence of digital communities, structured on reference hubs and standing out from the detected phenomenon, prevalence of idioms and even language structures. The relevant role of the emotional (French), ironic (Italian), protest (English) component is confirmed, but also the changing and fluid structure of the debate and the co-presence of many parallel discussion communities.

Objectives: We investigated AB0 blood groups prevalence according to preoperative and pathological tumor characteristics, and their association with oncological outcomes, and renal function decline in a contemporary large cohort of bladder cancer (BCa) patients, who underwent radical cystectomy (RC) at a tertiary referral center. Materials and Methods: We retrospectively evaluated data of patients with histologically confirmed and clinically non metastatic BCa, who underwent RC between 2014 and 2021 at our Institution. Kaplan-Meier (KM) plots and Cox regression (CR) models tested the relationship between AB0 blood groups and local recurrence-, metastasis-, cancer specific mortality-, and overall mortality-free survival. Logistic regression (LR) models tested the association between AB0 blood groups and renal function decline, defined as an estimated Glomerular Filtration Rate (eGFR) < 60 mL/min, at post-operative day 1, discharge and 6- months of follow-up. Results: Of 301 included patients, 128 (42.5%) had group A, 126 (41.9%) had group 0, 28 (9.3%) had group B, and 19 (6.3%) had group AB. Patients with group 0 developed higher rates of muscle- invasive BCa (p = 0.028) with high-grade features (p = 0.005) at last bladder resection, and less frequently received preoperative immunotherapy with Bacillus of Calmette-Guerin (p = 0.044), than their non-0 counterparts. Additionally, these patients harbored more advanced pathologic tumor stage at RC (p = 0.024). KM plots showed no differences among all tested cancer control outcomes between AB0 blood groups (p > 0.05 in all cases). Patients with group AB presented the lowest median eGFR at each time point. In multivariable LR analyses addressing renal function decline, group AB was independently associated with eGFR< 60 mL/min at discharge (Odds Ratio: 4.28, p = 0.047). Conclusions: Among AB0 blood groups, patients with group 0 exhibited the most aggressive tumor profile. However, no differences were recorded in recurrence or survival rates. Group AB independently predicted renal function decline at discharge.
